    This paper describes a verbal representation of a topographic map. First, we carried out an experiment that human subjects put a shape of two-dimensional functions drawn by contour lines in words. Next, we extracted some key words from the words used in the experiment and defined the key words by gradients of the functions' surfaces. Finally, we applied the key words to a topographic map and represented it in the key words. A correlation between mountains on the map, which was hard to be shown by contour lines, was distinctly given by the verbal representation.

    An inverted pendulum is stabilized by a robot arm with rubber pneumatic actuators. The arm is identified as a linear second order system with time lag by the step responses. The pendulum is described by a linearized dynamic model. A digital control law is designed and implemented in a personal computer, which is composed of an LQ optimal state feedback, a minimal-order observer, and a predictor for one sampling period (40 ms) and time lag (80 ms).

    This paper describes speed controllable cursor keys. The cursor keys which are discussed here have output speeds for an input force as follows :
    [1] linear,
    [2] three grades (zero, half and full),
    [3] logistic, and
    [4] exponential.
    Experiments on the above cursor performance were carried out. The experimental results are as follows : The exponential output cursor key showed the shortest positioning time of the four kinds of cursor keys. And it was different from other cursor keys in the positioning time especially when a target size was small (3 mm in diameter). The settling time, which is spent to fix a cursor on a target, of the exponential output cursor key is the shortest of the four kinds of cursor keys. But the pressing time of it is the longest of all. These results show that the exponential output cursor key is controlled by applying force on a key top and the other cursor keys are controlled by tapping time. Next, these cursor keys are compared with a mouse. The logistic output and exponential output cursor keys showed the same time as the mouse when the target size was large (12 mm in diameter).
